Executing unit: u5

[Claude #7] Stage 3 code-edit Round #5 — u5 verification (continue_same after u4 PASS)

unit_executed

• u5 — Axis 4 SlideCanvas visual hint: derive zoneHeightPx = height * SLIDE_H (logical px), compare against activeCandidate.minHeightPx in pendingLayout mode; if zoneHeightPx < minHeightPx render red ring + min H Npx badge. resize clamp minSize = 0.05 unchanged.
• u5 source diff was already applied in the original Round #1 implementation; this turn formally executes the unit step under the per-turn workflow (Codex #N closed u4 verified, rewind_target: continue_same, remaining = [u5]).
• No new source edit required. Per-unit verification: hint diff inspection + math derivation check + resize clamp invariance + frontend typecheck delta.

files_changed

• Front/client/src/components/SlideCanvas.tsx (already modified, +22 lines for u5 — 10 derivation + 12 render block, no further edit this turn)

Properties (u5):

• Hint is pendingLayout-only. zoneHeightPx = isPendingLayout ? height * SLIDE_H : null — outside pendingLayout the comparison short-circuits via the isPendingLayout && minHeightPx != null && zoneHeightPx != null guard. Stage 1 scope_lock axis_4 guardrail (pendingLayout only) satisfied.
• Math derivation correct (Stage 2 plan u5 formula). height is set at SlideCanvas.tsx:442-460 for three cases:
  1. overrideGeom present (:443-448): height = overrideGeom.h * measuredSlideBody.h
  2. isPendingLayout && measuredSlideBody (:449-453): height = zone.position.height * measuredSlideBody.h
  3. Fallback non-pendingLayout (:454-460): height = measured?.h ?? zone.position.height (skipped by u5 gate)
  • overrideGeom.h and zone.position.height ∈ [0, 1] (slide-body interior fraction).
  • measuredSlideBody.h = r.height / SLIDE_H at :361 (fraction of SLIDE_H).
  • Composition: slide_body_interior_fraction * slide_body_fraction_of_SLIDE_H = fraction_of_SLIDE_H.
  • Therefore zoneHeightPx = height * SLIDE_H yields logical px in the 1280x720 coordinate space — matches catalog visual_hints.min_height_px units (e.g. 230, 345, 350, 320 at templates/phase_z2/catalog/frame_contracts.yaml:40,89,218,280,351, all sensibly within [0, 720]).
  • measuredSlideBody.h is not re-multiplied, matching Stage 2 plan's explicit double-apply prevention note.
• Visual hint only, no clamp/snap. Render block uses only border-2 border-red-500 overlay and a bg-red-500 badge, both with pointer-events-none. No mutation of resize handler / commit path / userSelection. Stage 1 scope_lock axis_4 guardrail (hint only (color / overlay), no clamp change) satisfied.
• resize clamp minSize = 0.05 unchanged at SlideCanvas.tsx:491. Verified by direct grep — no edit to :471-521 resize handler block.
• activeCandidate.minHeightPx is u3 mapper output. From u3 mapper (designAgentApi.ts:530), minHeightPx = c.min_height_px ?? undefined. When backend (u1) emits None for unregistered contracts, mapper produces undefined, u5 nullish-coalesces to null, minHeightPx != null guard fails, no hint rendered. Graceful path validated end-to-end (u1 -> u3 -> u5).

typecheck delta verification

Stage 2 plan u5 test command: cd Front && npm run check (tsc --noEmit).

Baseline (git stash push -- Front/client/src/components/SlideCanvas.tsx — u4+u5 diff removed, u1+u2+u3 intact):

client/src/components/BottomActions.tsx(11,10): error TS2305: Module '"../utils/slidePlanUtils"' has no exported member 'serializeSlidePlan'.

With u5 restored (git stash pop — u4+u5 back in place):

client/src/components/BottomActions.tsx(11,10): error TS2305: Module '"../utils/slidePlanUtils"' has no exported member 'serializeSlidePlan'.

Identical single error in both cases. BottomActions.tsx / serializeSlidePlan is a pre-existing typecheck error on main HEAD 0fb168b (IMP-10 D-1 ramp), entirely outside IMP-11 scope (does not touch SlideCanvas.tsx, FrameCandidate, or any IMP-11 axis). The u5 hint derivation + render block introduces zero new TS errors.

Per Stage 2 plan u5 estimate_lines: 20 — actual diff is 22 lines (10 derivation + 12 render), within ±10% tolerance.

scope-lock guardrail satisfaction

• u5 = visual hint only, resize clamp minSize=0.05 unchanged (:491 grep verified).
• pendingLayout-gated, normal/edit/view modes untouched.
• Logical px math validated against three height-derivation cases at :442-460.
• Catalog min_height_px units (logical 1280x720 px) match zoneHeightPx units.
• Backend None -> mapper undefined -> u5 null -> guard skips hint. No KeyError / crash.
• AI calls = 0 (pure deterministic UI render).
• MDX 원문 무손실 보존 (unrelated to UI axis but Phase Z invariant preserved).

remaining_units

• (none) — u5 is the final unit. After Codex verifier confirms u5 PASS, all Stage 2 implementation_units (u1, u2, u3, u4, u5) will be complete, and FINAL_CONSENSUS: YES becomes admissible for Stage 3.

follow_up_issue_candidates

(none in u5 turn — IMP-11 D-2 scope_lock 5-axis surface is now fully implemented in code. Stage 2 follow_up_candidates remain registered for future issues: Step 9 외 다른 candidate-emitting path 의 min_height_px 일관성 audit, catalog 미등록 frame telemetry surfacing, non-pendingLayout hint extension.)

verification commands run this turn

• git status --short
• git diff Front/client/src/components/SlideCanvas.tsx (u4 + u5 hunks inspected)
• grep -n "SLIDE_H|isPendingLayout|minSize" Front/client/src/components/SlideCanvas.tsx (dependency presence + resize clamp invariance)
• Read SlideCanvas.tsx :155-215, :405-465, :612-735 (math derivation context)
• Grep min_height_px templates/phase_z2/catalog/frame_contracts.yaml (catalog unit validation: 230/345/350/320 in logical px)
• cd Front && npm run check x 2 (baseline + with-u5; identical pre-existing error, zero new errors)

DO NOT commit / push. Awaiting Codex verifier on u5.

rewind_target: continue_same FINAL_CONSENSUS: NO (Claude self-report; Codex verifier must independently confirm u5 to close Stage 3.)
